ASBESTUS CLOTH.

SPECIFICATION forming part of Letters Patent No. 290,239, dated December 18, 1883.

Application filed August 27, 1.883 (ModeLl To all whom it may concern Be it known that I, HENRY W. JoHNs, of Stamford, Connecticut, have made and in-. vented a new and useful Improvement in Asbestus Cloths, of which the following is such a full, clear, and exact description as will enable others skilled in the art to which this most nearly appertains to make and use the same, when taken in connection with the accompanying drawings, in which- Figure 1 is a face view of the fabric; Fig. 2, a cross-section through the loose rolls or rope; Fig. 3, a cross-section of the same through the loose rolls or ropes, showing the bindingthread. Fig. 4 is a longitudinal section of a modification of the rope; Fig. 5, a section of a modification. I

This my invention is an improvement in the manufacture of asbestus cloth, which has heretofore been made by weaving asbestus cord to-- This my invention is an improvement on the clothsheretofore manufactured, makinga much more firm cloth, and one easier of manufacture, owing to the peculiarities of the loose rolls of asbestus used in the manufacture.

To make a fabric according to my invention, the asbestus is broken into fiber and rolled,

gether, or weaving asbestus cord or rolls of as- -twisted, or formed into a roll or loose rope,

which forms the weft of the fabric, or what corresponds with the weft, as hereinafter described. This weft is knitted with a thread or cord of cotton or asbestus, or both combined, or with a fine wire, whereby several parts or sections of the rolls or ropes are held closely together and form the fabric, as shown in crosssection in Fig. 2.

- Instead of knitting the several rolls or ropes together, they may be sewed through, so that they will be held together, by the thread by which they are sewed. To make the fabric in this manner, it is best to feed the several rollssuccessivelyto several sewing-machines, so that each length of the roll or rope may be sewed at The thread or cord with or wire covered with asbestus or rendered fireproof in any manner, as by coating or saturating with non-combustible solutions or 1t may be made of pure asbestus. In the same fabric some of the lines of sewing or knitting may be done with wire and some with thread of either cotton, asbestus, or both. To prevent raveling 5 and produce a firm and strong fabric, the thread, cord, or wire may be coated with asol ution of india-rubber or other adhesive substance, whereby the loose roll or rope may be more firmly held. A very firm fabric may be produced by mixing or coating the loose roll or rope with a thin solution of india-rubber or other adhesive substance, or coating the finished fabric therewith. In making the loose rolls or rope for this fabric, theshort fiber of asbestus may be mixed with and used in the material put in them, and will be sufficiently held together by the knitting or sewing by which they are severally fastened to one another. The finished sheets may be used alone 7 or attached to other sheets-such as cloth, asbestus sheathing, wire-cloth, sheet metal, wood, or like materialas shown in Fig. 5. r The fabric made as above described, or made from loose rolls of fibrous asbestus woven with 7 5 wires or threads, may be compressed and treated or saturated with silicate of soda or other suitable material, so that it will be rendered compact and held in a firm and compact form, in which form it may be used for blinds, I doors, or partitions, either with or without frames or other similar devices.

The fabric made as above described, or made by weaving the loose rolls of fibrous asbestus woven with wires or threads, may be napped on the surfaces, either or both, which will give it greater powers as a non-conductor of heat. The napping may be accomplished by passing over the surface of it a picker, which pulls up a portion of the asbestus, thereby forming a I nap. The nap thus made may be coated with sizingsilicate of soda or like materialas cotton wadding is coated, and a good surface given to the fabric.

I do not claim herein the formation of a fab- 5 ric by weaving loose and compressible cords or ropes with cords or threads, as that forms the subject-matter of the claim of ,my application No. 32; 908.

What I claim as new, and desire to secure by 10o Letters Patent, isv

1. The combination of the loose and com pressible cord or rope united into a fabric by the small strands by knitting or sewing, substantia-lly as specified.

2. The combination of the loose and com- 5 pressible cord or rope united into a fabric by small strands coated with an adhesive substance by knitting or sewing, substantially as specified and set forth.

3. The combination of a loose and com 10 pressible cord or rope and small strands uniting the same into a fabric, the surface thereof being mapped, as specified and set forth.

4. The combination of a loose and compressible cord or rope and small strands unit- 15 ing the fabric, the surface thereof being coated with an adhesive substance, as specified and set forth.

5. The combination of a loose and compressible cord or rope and small strands uniting the same into a fabric, and coated with a 20 solution of india-rubber or like compound, substantially as specified.

6. The combination of the herein-described fabric and other sheets united by cementing them face to face, as specified and set forth.
